| Abstract: | The aim of the research work lies in improving weld quality for automatic submerged-arc welding of 20g steel.In the article is used the axial field with the bidirectional pulses for stirring the welding puddle so as to fine the primary crystalline structure in the weld metal, to reduce uneven chemical compositions, to improve plasticity and toughness of the weld metal and to increase the percent of pass to its cold bending angle.The article discusses mainly the operating principles of electromagnetic stirring in the puddle. |
